Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a potato harvester. Background Art

[0002] Potatoes are an important economic crop in my country and are grown in a wide area. In potato planting, harvesting is the last link in field operations. The choice of harvesting time and the quality of harvesting directly affect the yield and commercial value.

[0003] Most harvesting methods are mechanical or manual digging, of which manual digging takes up more man-hours. Since manual digging of potatoes for harvesting also requires manual picking of potatoes, the harvesting efficiency is low, and most of the harvested potatoes are covered with soil.

[0004] When digging and harvesting potatoes, the potatoes are mixed with the soil, which is not convenient for workers to pick up and load for transportation. After digging the potatoes, the potatoes are placed messily on the soil, which is not conducive to picking up. Moreover, the soil after digging is uneven, and the potatoes are easily blocked by the soil and easily missed when picked up. Utility Model Content

[0005] The utility model aims to provide a potato harvester which has the characteristic of improving harvesting efficiency.

[0007] In order to facilitate the harvesting of potatoes, as a preferred potato harvester of the utility model, a second fixed cylinder is fixedly installed on the rear of the frame, a second movable rod is movably sleeved on the inner side of the second fixed cylinder, a mounting seat is fixedly installed on the lower end of the second movable rod, and a wheel is rotatably installed on the inner side of the mounting seat.

[0008] In order to remove the mud on the outside of the wheel, as a preferred potato harvester of the utility model, the top of the second fixed cylinder is threadedly installed with a turning handle, the lower end of the turning handle is rotatably installed with the top of the second movable rod, and a mud scraper is fixedly installed on one side of the mounting seat, and the mud scraper contacts and slides with the wheel.

[0009] For support and fixation, as a preferred embodiment of the potato harvester of the present invention, the digging plate corresponds to the position of the conveyor belt and does not contact it, and a support rod is fixedly installed on the top of the frame.

[0010] In order to dig potatoes, as a preferred potato harvester of the utility model, first fixed cylinders are fixedly installed on both sides of the frame, a first movable rod is movably sleeved on the inner side of the first fixed cylinder, and one side of the first movable rod is rotatably installed with the soil cutting disc.

[0011] For the convenience of adjustment, as a preferred embodiment of the potato harvester of the present invention, a locking screw is provided on one side of the first fixing cylinder, and the first fixing cylinder is pressed and abutted against the first movable rod through the locking screw.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The potatoes are pushed out of the soil by the digging plate, and the soil is flattened by the roller driven by the connecting rod. The potatoes are transported and filtered by the conveyor belt and transported between two gear bars. The harvested potatoes are gathered into ridges through the gear bars and fall onto the flattened soil, making it convenient for workers to load them into the transport vehicle, thereby collecting the potatoes, reducing the tediousness of workers in searching and picking up the excavated potatoes from the soil, and improving the efficiency of workers in collecting potatoes.
